Non-Small Cell Lung Cancer Is A Group Of Lung Cancers
Non-Small Cell Lung Cancer (NSCLC) is a type of lung cancer
that accounts for approximately 80-85% of all lung cancer cases. It is
characterized by the presence of large, irregularly shaped cells that do not
resemble normal lung tissue. NSCLC can occur in any part of the lung and can
spread to other parts of the body through the bloodstream or lymphatic system.
There are several subtypes of NSCLC, including
adenocarcinoma, squamous cell carcinoma, and large cell carcinoma.
Adenocarcinoma is the most common subtype and typically occurs in the outer
part of the lung. Squamous cell carcinoma occurs in the central part of the
lung and large cell carcinoma can occur in any part of the lung.
The causes of Non-Small
Cell Lung Cancer
are not fully understood, but smoking is the most significant risk factor.
Other risk factors include exposure to radon, air pollution, and certain
industrial chemicals. People with a history of lung disease, such as chronic
obstructive pulmonary disease (COPD), are also at an increased risk for NSCLC.
Symptoms of Non-Small
Cell Lung Cancer
can include a persistent cough, chest pain, shortness of breath, and weight
loss. However, these symptoms are often non-specific and can also be caused by
other conditions. Therefore, it is important for individuals who have risk
factors for NSCLC to be screened regularly.
Diagnosis of NSCLC typically begins with a chest x-ray or CT
scan. If a tumor is found, a biopsy may be performed to obtain a sample of the
tumor tissue for further analysis. The stage of the cancer, which refers to the
extent to which the cancer has spread, is also determined.
Treatment for NSCLC depends on the stage of the cancer and
the overall health of the patient. Surgery, radiation therapy, and chemotherapy
are the most common forms of treatment. Surgical options include lobectomy,
which involves removing a lobe of the lung, and pneumonectomy, which involves
removing an entire lung. Radiation therapy and chemotherapy can be used alone
or in combination with surgery.
